Yup, you're quite right, realised that just after I hit 'send'! I'm working on 
getting boundary line into a DB as we speak, but it's quite a monster!

Isn't that actually the council for the closest postcode to that lat/lon
though, which isn't precisely what's asked for.

I wrote some simple Django example code at the weekend to import
Boundary-Line into a database:
    http://github.com/dracos/opendata-boundaryline

It's then as trivial as:
    point = Point(400000, 300000)
    Council.objects.filter(shape__contains=point)

I'd certainly recommend getting shapefiles into some sort of spatial
database nowadays, it makes things very easy.

ATB,
Matthew
